Building and sim games are much more fun and challenging when players have to build something that's out of this world. Thanks to some of the most complex and fun video games set in space gamers can not only explore other universes but build all kinds of futuristic sci-fi and fantasy spaceships.

While these spaceship-building games tend to be more complex and complicated it doesn't mean that beginners or casual gamers shouldn't try them. Players can go on epic adventures while playing with some of the best sci-fi games in which they can not only pilot but build gorgeous and super fast spaceships to explore other planets, stars, and complete solar systems. Some of these fascinating games can even help players learn and improve their real-world knowledge regarding psychics, engineering, and of course space exploration and astronomy.

Updated October 6, 2024, by Hamza Haq: The fantasy of the building, customizing, and driving a spaceship through the vast emptiness of outer space has always had a pull for gamers that's undeniable. It's a core part of what the science fiction genre is based on and an aspect of what drives the popularity of major franchises like Star Wars and Star Trek. It's no coincidence, then, that games that revolve around building new spaceships or customizing existing ones have always had a place in the gaming scene and a dedicated audience.

11 Forever Skies

  • Release date: June 22, 2023
  • Developers: Far From Home
  • Genres: Adventure, Simulation, Indie

Forever Skies is a post-apocalyptic survival game where players return to a ravaged Earth with futuristic technologies in hopes of harvesting something of value from it and uncovering the secrets that led to the widespread toxic mist that now envelopes everything on the planet.

The game shares a lot of similarities with Subnautica, mainly in the form of its fabrication, first-person perspective, and scanning system. However, there are some key differences as well. Instead of creating multiple bases across the sea, Forever Skies asks players to develop their airship, a sort of blimp that can soar through the sky. This also doubles as a base of operations and a HUB area for all survival activities. Having a moveable base is a twist of the survival genre formula that, while rare, isn't unheard of. But one that flies? That's something new. Players can add modules to this airship as they unlock and develop new technologies, which increase the ship's effectiveness in multiple ways.
